I do not understand please explain the picture
thanks

On a board are torn off and there are no printing places. I have shown a way for soldering of jumpers.If you make so jumpers the hold button will work.
What you want? In the first post you have written that the hold button doesn't work. You after all want to repair this button?
If to you my picture isn't clear, open the schematics and look there. I hope in the schematics to you it will be clear.
